How To Migrate Field Collection to Paragraph in (From Drupal 7 to Drupal 8)

General Steps How To Migrate Field Collection (Drupal 7) to Paragraph in Drupal 8

#1 Install and enable the Paragraphs module on your Drupal site.

#2 Create a new Paragraphs bundle for each of your Field Collection bundles. A Paragraphs bundle is like a new field type that you can add to your content type. You can specify the fields that should be included in the Paragraphs bundle, and you can also configure the appearance of the Paragraphs bundle. Make sure that you create a Paragraphs bundle for each Field Collection bundle that you want to migrate.

#3 Create a new Paragraphs field on your content type. When you add a new field to your content type, choose “Paragraphs” as the field type. Then, select the Paragraphs bundle you created in step 2. Make sure that you create a new Paragraphs field for each Field Collection field that you want to migrate.

#4 Migrate your data from Field Collection to Paragraphs. You can use a module like Migrate or Drupal’s built-in migrate tools to migrate your data from Field Collection to Paragraphs. This will involve mapping the fields in your Field Collection to the fields in your new Paragraphs bundle. Make sure to test your migration thoroughly to ensure that your data is being migrated correctly.

#5 Remove the old Field Collection field from your content type. Once you have migrated your data, you can remove the old Field Collection field from your content type. This will ensure that you are no longer using the Field Collection module.

It’s important to note that there may be some differences in functionality and usage between the two modules, so you may need to make some adjustments to your content structure or workflow.

The Migration Steps

#1 Install the Migrate and Migrate Drupal modules. These modules provide the functionality to migrate your data from one content type to another.

#2 Define the source and destination of your migration. You will need to create a migration YAML file that defines the source (Field Collection) and destination (Paragraphs) of your migration. In this file, you will specify the fields that you want to migrate and how they should be mapped from the source to the destination.

#3 Define the migration process. In your migration YAML file, you will also need to define the migration process. This includes specifying any necessary transformations or manipulations of your data, such as mapping between different field types.

#4 Run the migration. Once your migration YAML file is defined, you can run the migration using Drupal’s built-in migration tools. You can do this using the Drupal command-line interface (CLI) or through the Drupal user interface.

#5 Test your migration. After your migration is complete, you should thoroughly test your data to ensure that it has been migrated correctly. This includes verifying that the fields in your Paragraphs bundle are populated with the correct data from your Field Collection.

The YAML File

Here’s an example migration YAML file that migrates a Field Collection field called “field_my_collection” to a Paragraphs field called “field_my_paragraphs”:

id: migrate_my_collection_to_paragraphs
label: Migrate my Field Collection to Paragraphs
migration_group: my_migrations
source:
  plugin: entity:field_collection_item
  # Specify the Field Collection field that you want to migrate
  field_name: field_my_collection
destination:
  plugin: entity_reference_revisions:paragraph
  # Specify the Paragraphs field that you want to migrate to
  default_bundle: my_paragraphs_bundle
process:
  # Map the Field Collection fields to Paragraphs fields
  field_paragraph_field_one:
    plugin: sub_process
    source: field_field_collection_field_one
    process:
      value: value
  field_paragraph_field_two:
    plugin: sub_process
    source: field_field_collection_field_two
    process:
      value: value

In this example, the migration YAML file defines the source (Field Collection) and destination (Paragraphs) of the migration, as well as the fields that should be mapped between the two. Once you have defined your migration YAML file, you can run the migration using Drupal’s built-in migration tools.

Place the YAML file

When using the Migrate module in Drupal, you typically place the YAML file defining your migration in a custom module or theme. Here are the steps to do so:

#1 Create a new custom module or use an existing one.

#2 Create a subdirectory inside your custom module called “migrations”. This is where you’ll place your YAML files defining your migrations.

#3 Create a new YAML file inside the “migrations” directory that defines your migration. You can give the file any name you like, but it’s a good idea to use a descriptive name that reflects the purpose of the migration.

#4 In the YAML file, define your migration using the Migrate API. This includes specifying the source and destination of the migration, as well as any necessary transformations or manipulations of your data.

#5 Save the YAML file and enable your custom module. Drupal will automatically discover and load any migration files that you place inside your custom module’s “migrations” directory.

Once you’ve placed your YAML file inside your custom module’s “migrations” directory, you can use Drupal’s built-in migration tools to run the migration. This includes using the Drupal command-line interface (CLI) or running the migration through the Drupal user interface.

Another Way: Using Field Collection to Paragraphs Migration module

Field Collection to Paragraphs Migration module, which provides a simple one-click migration process from Field Collection to Paragraphs. This module automates the process of creating a new Paragraphs field for each Field Collection field on your content types, copying over the data from your Field Collection fields to the new Paragraphs fields, and updating your content types to use the new Paragraphs fields instead of the old Field Collection fields.

Here are the basic steps to use the Field Collection to Paragraphs Migration module:

Install and enable the Field Collection to Paragraphs Migration module.

1. 1. Go to the module configuration page at /admin/config/content/fc2p.
   2. Select the content types that you want to migrate from the list of available content types.
   3. Click the “Migrate selected content types” button to begin the migration process.
   4. Wait for the migration process to complete. The module will display a summary of the migration results when it’s finished.
   5. Verify that your content types are now using the new Paragraphs fields instead of the old Field Collection fields.

Note that while the Field Collection to Paragraphs Migration module is designed to automate the migration process and make it as easy as possible, there may still be some manual cleanup or adjustments required depending on the complexity of your content types and fields. However, using a tool like this can still save you a lot of time and effort compared to manually migrating your content.
